He is planning to create a bar graph with a scale in 5% increments. Is this an appropriate choice given the data? Why or why not? No, he should construct a pie chart instead.No, he should use a scale with larger increments such as 0, 10, and 20.Yes; since his percentage does not go above 15% he can use a scale with 0, 5, 10, 15.No, because his percentages are so close together it will be difficult to determine differences in the years if he uses a scale of 5% increments. He should use a smaller scale such as 1% increments.Use the following graph for question 2.The solution set to the system of inequalities is graphed.
